Vedic astrology is one of the vedangas of the Vedas, the ancient Hindu scriptures. The vedangas are the six sciences that are studied in order to practice and understand Vedic teachings. In Vedic astrology, a person's destiny is determined by his/her karma, which is set forth in the cosmic design.
Vedic and Western astrology have some similarities, including the 12 signs of the zodiac, but Vedic astrology emphasizes the rising sign at the precise moment of birth rather than the 30-day sun sign. Also, the difference between the sun signs in the two systems of astrology is said to be 24 degrees, meaning that one might identify with a different constellation. In Vedic astrology, a master astrologer, known as a jyotish acharaya, uses a variety of charts to further refine the individual's horoscope.
